To all whom it may concern: I

Be it known that I, JOHN R. Rooms, of the borough of Brooklyn, county of Kings, and State of New York, have invented a new and useful Improvement .in Line-Casting Machines, of which thefollowing is a specification. This invention has reference to line casting machines, in which circulating matrices are assembled in l ne, the line presented momentarily to the face of a slotted mold in order to form type characters in a slug cast therein, and the 'JDtLtI'lCQS thereafter distributed preparatory to their main new now in extensive commercial use, and fa-Q miliar' to all persons. skilled in the art.

The object of the invention 18 to secure the speedy and accurate composition of what is known as tabular matter thatis-to say matter in which the figures or other characters in one line fall directly below those in the lineabove, that they may appear in vertical columns in the print,'with1 or without vertical rules between the columns.

To this'end the invention consists in means whereby "oups of matrices in the composed line, helonging to separate columns, are, held in definite'positions before the-mold, in order that the vertical'rules or spaces between the" columns will register ex actly on thehdjoining slugs in the form. The invention also consists in the combination of means for composing each matrix line in'groups of definite length, with means for maintaining the proper relationship of these groups when presented to the mold.

' Thevinvention consists also in combining with thecompo sed. groups. of matrices, and. means for malntalningtheir positlons n front of the mold,-,expansible spacers or justifiers for the respective groims'. and means for advancing and expanding the spacers .exactly justifiecl.

will he hereinafter described;

In the drawings,-'Figure 1 is a perspective view of tabular slugs such as my mechanism is designed to produce, these slugs having shallow. slots to receivethe vertical column rules. Fig. 2 is a perspective view of tabular slugs of another form which may be produced by my mechanism, the column rules being formed upon the slugs.

that the composed line may be raised bodily from the assembling level. I

The elevator I serves to lower the line to the castingrlevelin front .of'the mold, and also to raise it fromsaid level to to the distributing devices.

mechanism by which the line is transferred J is a vertical wheelfo r diskin which the I slotted'mold-K is mounted. This disk is carried by a centralstud L, on a horizontal slide, by which the mold is moved facewise, to andfrom the line of matrices, when the line is sustained in the casting position as shown in Figs. 7 and v8.

So far as described the parts may identical with those in the commerclal Mergenthaler machines above referred to. v

The line of matrices is composed in the,

assembler D, lifted by the latter between the fingers of the carriage Ggand thereafter transferred by' this, carriage 'through the support H into the elevator I, by which. the line is finally lowered tothe casting position in front of themold as shown in Fig. 8. xAt

the time the line is thus lowered the mold in its retracted position. After the line reaches its final level the mold advances facewise against the matrices as shown in .8, so that the lower edgefof the mold in existing machines.

of the foregoing actions beingthe same as In carrying my invention into effect I first provide means for assembling in one line the groups of matrices corresponding in width to the width of the respective columns in'the table to be printed. For this purpose I prefer to use the' mechanism shown in Fig.

6 and covered by Letters. Patent of the United States No. 924,000, dated June 8, 1909,'the assembler slide F being provided with thin vertical fingers f secured, in place by screws f and adjustable laterally along the bar, so that they may be placed at dis-v tancesf apart corresponding to the required widths of the gran s of matrices in the line," orfin other words is e widths of the columns."

By the operation of the machine the matrices are "delivered automatically between these fingers.;

At the end ofeach group I deliver to the line a wedge spacer or justifier Y such as commonly used in the Mergenthaler machines,

and described in Patent No. 436,532, each consisting of two oppositely tapered wedges connected by a" sliding 'joint, so that the longer wedge may be thrust upward through the line while its companion remains at reel in ,orderto increase the width'or thickness oflthe operative portion in the line. The

In other words, the independently adjustable spacers will effect the exact justification of the several. groups'to the. predetermined lengt 'Afterthe composition of theline is completed it is lifted andti'ansferred to the casting position in-front of the mold, as before explained. When the line is lifted from the assembler slide. F, the spaces represented by the fingers f exist between the groups, but

the fingers of the carriage G serve. to close the matrices together into a compact or continuous line preparatory to its transfer to the mold. .When in front of the mold, the v matrixline is confined endwise between the" 'usual jaws M, by which its'total length is determined; v

a In order that the individual groups may be held in their proper relations before the mold and each oup limited to its, proper length,-I-fix rigi ly to the face of the mold a horizontal bar, N, having at the forward 'edg'e pointed teeth of uniform width, the notches 91. between these teeth being adapted to receive and hold the. lips a on the space matrices or spaces C whereby thesespaces' are prevented from shifting sidewisel notch it isimmaterial, as the pointed shape of theteeth; will-move the space right or left to its proper position as the mold advances toward the matrices. It will be seen that the spaces have their forward edges held securely against lateral movement, and that being. thus held they determine exactly the lengths of the several groups of matrices inthe line.

As the matrices which can be inserted 1n any one group will occasionally fail to exactly fill the allotted space, extensible spacers or justifiers, Y,are employed to fill this slight remaining space, which will rarely exceed 1/1000 of an inch. When the spacers are pushed up through the line the groups justified independently between two of the,

' fixed spaces C or between one of these are expanded or filled out tightly between the spaces, so that a solid matrix line is 'presented to the mold, the line being composed.

of groups of the predetermined length.

Owing to the fact that the spaces between the groups are held in definite positions, it is possible to make the groups of one line agree exactly in width with those of the succeeding lines.

As the space to be filled in the several groups may vary, it is necessary to provide for the justification of each group independently of the others. This result is secured by providing a yielding pusher to act upon the longer wedges in series. In the form shown this mechanism consists of the usual vertical, movable bar 0, provided on its upper surface' with a strip of rubber, P, or equivalent elastic material. When this bar is carried upward it acts upon the series of justifier wedges and drives them upward through the line, each wedge being lifted independently of the others until its advance arrested by the resistance of the adjacent matrices. Each group of matrices is thus spaces and a jaw M at the end'of the line. In place of the elastic strip P any other de-. vice may be used which shall apply upward pressure to the wedges Y regardless of their positions.

When s' l are to be produced, I employ matrices such as shown in Fig. 3, deeply notched at the front and having the matrix proper at the bottom of the notch, so that when'a series of these matrices are arranged in front of the mold they will form a continuation of its slot, the slug being cast partly in the mold and partly in the matrices, as explained in Patent 791,165.

lotted slugs such as shown inFig.

slugs'I employ spaces C suchas shown'in Fig. 3, these spaces being without the notch in the front edge,.as explained in the patent above named. They are, however, provided with the lip 0 to engage the locking bar N.

ing the vertical rules 6 cast thereon are to be produced, I employ matrices and spaces such as shown in Fig. 4, the matrix having the character or matrix proper in one edge near the surface, and the space having the rule matrix in its ed gein corresponding position. This space is provided, as before explained, with a lip, a, to engage the locking bar of the mold.

When the slugs are to. be cast without the .say simply with blank spaceshnween the groups of characters, I use instead of the rule matrix shown in Fig. 4, a blank space 01' matrix such as commonly used in Mergenthaler machines, but with a lip 0 thereon.

While I prefer to make use of the toothed curing the spaces in the line against lateral movement, it is to be understood that the form of the locking device and the form of the matrices may be modified at will, provided only the locking devices are adapted "to engage in such manner as to hold the spaces rigidly in the predetermined positions.

slot to produce slugs for printing entire linesof a page or column, it is manifest that molds divided into a number of short lengths well known in the art, may be used in connection with my means for determining the length and location of the several matrix groups.
